High - speed stripper can effectively wipe off returning flow of fibres and decrease stopping rate , thus protecting doffer card clothing
高速清潔輥有效去除返花，降低停車率，保護(hù)道夫針布。
Instead of closed boundary conditions which will bring large pressure effects because of return flow , a flow through boundary condition is adopted
該模型的主要特點(diǎn)是采用開放邊界條件，從而可以避免原有封閉模型因回流問(wèn)題而產(chǎn)生的復(fù)雜效應(yīng)。
Glenn noted the water that percolates out from normally irrigated soil , technically known as irrigation return flow , is often as salty as 10 percent seawater
格倫指出，從淡水灌溉的土壤滲出的水，專業(yè)名稱叫做“回流” ，通常它的含鹽度也相當(dāng)于像海水鹽度的10 % 。
When soil antecedent condition is dry and the initial rainfall intensity is high , peak surface runoff also considerably lag behind that of rainfall , because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response , only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism , and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h , indicating the existing of macropores and pipe flow in cultivated layer
2 )耕作制下紫色土的產(chǎn)流主要機(jī)制是： 1 )當(dāng)雨前土壤含水量未達(dá)到飽和狀態(tài)時(shí)，表面產(chǎn)流起始時(shí)間有明顯滯后現(xiàn)象，這與紫色土的快吸水性和較多非毛管孔隙密切相關(guān)；當(dāng)雨前土壤較干燥，降雨初期雨強(qiáng)較大時(shí)，易形成臨時(shí)相對(duì)不透水表層，表面產(chǎn)流峰也有明顯滯后現(xiàn)象。 2 )表面徑流的產(chǎn)流方式主要是超滲產(chǎn)流，當(dāng)土壤達(dá)到飽和狀態(tài)后，有四川大學(xué)博士學(xué)位論文小部分回歸流發(fā)生，但主要是飽和超滲產(chǎn)流發(fā)生，因?yàn)樽仙恋南鄬?duì)不透水層和其它透水障礙層不明顯。 3 ）壤中流主要是飽和產(chǎn)流，與降雨過(guò)程有明顯的滯后，而且雨停后的壤中流產(chǎn)流歷時(shí)與降雨特征無(wú)關(guān)。
In this way , when obturation cubage leave absorb oil cavity it connects the eduction oil cavity with the v trough and with the increasing of the turning angle , the size of the cross section of v trough become bigger and bigger , which make the pressure between the cavity of two blades much higher and higher , and until it completely connects the eduction oil cavity , it reaches the pressure of the eduction , and it can effectively reduces the fluid noise caused by high pressure return flow
這樣，當(dāng)密閉容積離開吸油窗口之后，通過(guò)v型尖槽逐漸與排油窗口連通，隨著轉(zhuǎn)角的增加， v型尖槽通流截面積逐漸增大，這就使兩葉片間容腔內(nèi)的壓力逐漸升高，直至完全接通排油窗口時(shí)，才升壓達(dá)到壓油腔的壓力，這樣可以有效地降低因高壓回流而引起的流體噪聲。
Fluid noise mainly comes from out put pulsation of rate of flow , the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition . the v trough on the port plate can reduce the fluid noise . in this paper , the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12 . 3 and its length was 5mm and the cross section was an equilateral triangle
流體噪聲主要來(lái)源于輸出流量脈動(dòng)，造成輸出流量脈動(dòng)的主要原因是閉死容積在大圓弧段壓力切換時(shí)產(chǎn)生的瞬時(shí)高壓回流，在配流盤上開設(shè)v型尖槽可降低因高壓回流而引起的流體噪聲，本文以截流作用和液體的可壓縮性為理論依據(jù)，以matlab語(yǔ)言為工具，對(duì)原配流盤上的v型尖槽進(jìn)行了理論計(jì)算，繪制出p - t圖線，分析了它的不足，并對(duì)原有v型尖槽進(jìn)行了優(yōu)化設(shè)計(jì)，得出了v型尖槽的最佳幾何尺寸：配流盤平面上的v型尖槽的兩邊的夾角為12 . 3 ，槽長(zhǎng)5mm ，槽的橫截面為等邊三角形。
